RESUMEN
OBJECTIVE:To put forward a proposal for the name standardization of Chinese herbal pieces. METHODS:Through searching literatures and analyzing each edition of Chinese Pharmacopoeia,the existing problems about the name of Chi-nese herbal pieces in the 2015 edition of Chinese Pharmacopoeia were found out to put forward solutions. RESULTS & CONCLU-SIONS:There are many non-standard problems,such as non-standard name of crude Chinese herbal pieces,non-standard name of processed Chinese herbal pieces,jingandganadded before the name of Chinese herbal pieces,pianadded after the name of Chinese herbal pieces. Based on these problems,suggestions for naming processed and non-processed Chinese herbal pieces were put forward,including noting processing method before the name of Chinese herbal medicines,adding processed form name after the name of Chinese herbal medicines,adding accessories name before the name of Chinese herbal medicines,maintaining the consistency and completeness of the names of Chinese herbal pieces and medicines,must markingshengwhen using toxic Chi-nese medicine pieces in medical treatment,and no appearing of the tablets in the name,etc.
RESUMEN
OBJECTIVE:To optimize extraction technology of saponins from Paris polyphylla. METHODS:Using paris sapo-nin Ⅰ,paris saponin Ⅱand Paridis total saponin as dependent variables,using ethanol volume fraction,extraction time and sol-vent amount as independent variables,through multiple linear regression and binomial fitting,the extraction technology was opti-mized with response surface method and predicted. RESULTS:The optimized extraction technology of saponins from P. polyphylla was as follows as 10-fold of 80% ethanol,2 times reflux extraction,100 min each time. Under the extraction technology,the ex-traction rates of paris saponinⅠwere 85.4%,82.7% and 87.1%;those of paris saponinⅡwere 85.9%,81.3% and 83.6%;and those of Paridis total saponin were 89.5%,92.1% and 90.3%(all RSD<2.0%). Measured value was 0.964 9,predicted value was 0.986 0 and deviation rate was 2.14%. CONCLUSIONS:The central composite design-response surface method is simple and reliable for the optimization of extraction technology of saponins from P. polyphylla.
RESUMEN
Objective To research the forming technology of Chuansu Jiuxin dropping pills.Methods The pills were prepared by dropping method.The forming technology of the pills was optimized by single factor test and orthogonal experiment by using the amount of PEG4000 to PEG6000, ratio of drug-matrix ,dropping temperature and speed as factors and with pill weight RSD,the time limit of collapse and appearance quality of the pills as evaluation indexes.Results Using PEG 4000 and PEG 6000 as matrix with the ratio of 4:1 and dimethyl silicone oil(100 mPa· s)as refrigerant at 5~15℃,the optimized parameters for the forming technology were as follows:the ratio of herbal extract to matrix was 1:3,the dropping temperature was at 90 ℃ and the dropping speed was 35 drops per minute,dropping from 4 cm.Conclusion The optimized technology is sample and feasible,and can provide a reference for industrial production of Chuansu Jiuxin dropping pills.
